摘要： Systems and methods are described herein for reducing electromagnetic interference (EMI) affecting measurements of a battery module monitoring board. A battery module system includes battery cells on a top side and a bottom side of the battery module. Each battery cell is electrically coupled between an adjacent pair of busbars. Each busbar is coupled to at least one sensor wire. One busbar, which spans the top and bottom sides of the battery module, is coupled to two sensor wires such that EMI interference affecting measurement signals (e.g., noise signals accompanying voltage readings) associated with the top side of the battery module are in-phase with one another and the measurement signals associated with the bottom side of the battery module are in-phase with one another, such that the EMI interference generally cancels in measurement calculations.

摘要： In accordance with one embodiment of the present invention, an aircraft comprises a battery pack mounted external to the aircraft structure. The batteries are configured to vent directly to the environment during battery thermal runaway. In one embodiment, an aerodynamic fairing provides an aerodynamically efficient surface and weather protection during nominal flight conditions. During battery thermal runaway however, the aerodynamic fairing is configured to expose the battery to the environment.

摘要： The present application relates to a harness isolation plate assembly, a battery module, a battery pack and a device. The harness isolation plate assembly includes a plurality of isolation units comprising busbars and insulating films connecting the busbars; and a connecting assembly through which the adjacent isolation units are connected. In the present application, the harness isolation plate assembly includes a plurality of separate isolation units. Upon molding, each isolation unit can be processed independently. Moreover, a size of each isolation unit is small, thus reducing processing difficulty. Furthermore, it is easy to control a location of each busbar, such that locating accuracy of the busbars is improved so as to enhance connecting reliability between the busbars and an electrode lead. Meanwhile, in each isolation unit, the busbars are connected through the insulating films, such that a risk of short circuit for the busbars is low.
